We're dividing 514849 by 12 
We want to figure out the number of times 514849 can be divided by 12.

Step 1:
When dividing 5 by 12, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 12

Let's proceed to step 2:
When dividing 51 by 12, we get 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 48 from 51, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 12

Advancing to step 3:
The number 12 fits into 34 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we take 24 away from 34, we end up with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 12

Going ahead to step 4:
If we divide 108 by 12, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 429.0
Deduct 108 from 108 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 12

Let's proceed to step 5:
If we divide 4 by 12, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 4290.0
Subtract 0 from 4 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 12

Advancing to step 6:
The number 12 fits into 49 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 42904.0
The remainder is 1 after subtracting 48 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 42904.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 42904.08
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 42904.083
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 42904.0833
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 42904.0833 with a remainder of 4e-05.
